springboot+mybatis+pagehelper分页，排序

引入依赖

<!-- mybatis的分页插件 -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.2.13</version>
        </dependency>

orderBy 格式为 排序字段 空格 排序方式  (id desc)

 

 service层使用工具类包装  PageHelper分页， PageInfo分页数据转换

    @Override
    public PageInfo<UiFlowModel> selectAll(int pageNum,int pageSize ,String orderBy) {
        PageHelper.startPage(pageNum,pageSize,orderBy);
        List<UiFlowModel> models = uiModelMapper.selectAll();
        PageInfo<UiFlowModel> pageInfo = new PageInfo<>(models);
        return pageInfo;
    }

debug 查看 pageInfo 

 

controller 手动去包装就好
